From what I understand.. the 2 amps is a trickle charge and is better.. the 10 Amps is for a fast charge.. so.. 2 amps

Check the electrolyte level 1st and if low, add distilled water and WAIT 2-3 days to absorb, then charge @ 10-amps overnight.
Do NOT overfill, but if/when too low ... once a plate sulfates it is dead forever.
Also note the correct state of charge (via multimeter [OK] or hydrometer [best]) cannot be read for ~24-hours or so AFTER the battery has been charged, to allow the surface effect to dissipate.

... it'll take DAYS to charge @ 2-amps ... not recommended for a dead battery.

Use automatic charger and charge at 2 amps for the first 2 hours. Crank up to 10 amps until charged. Switch back to 2 amps and charge for at least 12 hours. This is the way most fully automatic chargers operate in Deep Cycle mode. If you have Dry cell or Gell cell batteries charge with appropriate charger or a fully automatic charger set at 10 amps. Never leave a manual charger on a battery for extended periods of time. If you leave a lead acid battery dead it will be dead for good...especially if it freezes.
